Title: Dielectric antenna
Inventor: YANO KOUJI
IPC: H01Q13/22
Filed: 1979-10-02
Abstract: PURPOSE:To improve the directivity of a radio-wave beam by shortening the wavelength in a waveguide-shaped dielectric by forming a metal film around the dielectric by vapor deposition or plating. CONSTITUTION:On the entire surface of dielectric 1 having dielectric constant epsilonr except convex radio-wave radiation opening parts 4 formed at fixed intervals, thin metal film 2 is formed by vapor-deposition or plating and the entire surface of thin film 2 is molded with molding material 3 to a thickness equal to the height of the convexes. In this case, size l in the long size direction is determined satisfying the set expression based upon the relation of wavelength lambda0 of a radio wave to be used and dielectric constant epsilonr. Thus, miniaturization in terms of size and reduction in weight can be attained as well as directivity improvement and further since the thin metal film is hermetically sticking to the dielectric, the generation of an arc entailing an electric power loss can be eliminated without decreasing the dielectric constant equivalently.

Title: Semiconductor laser element and manufacture thereof
Inventor: SHIGE NORIYUKI
IPC: H01S5/00
Filed: 1987-05-27
Abstract: PURPOSE:To obtain a semiconductor laser element having small astigmatism by forming the principal section of a resonator in the structure of longitudinal multimode oscillation while at least one end section of the resonator is shaped index guide structure for longitudinal single-mode oscillation. CONSTITUTION:A central principal section extending over 60%-80% of a resonator 3 is formed in a narrow width resonator section 4, width (c) of which is as narrow as 3-5 mum. Both end sections of the resonator 3 are shaped in a wide resonator sections 5, width (b) of which is, for example, 5-10 mum. Since the resonator 3 is wide in the wide resonator section 5, the edge faces of the resonator 3 are not likely to be deteriorated and an electrostatic breakdown level is elevated, thus allowing the increase of an output. Since the thickness of P-type clad layers in the wide resonator sections 5 is shaped thinly, a longitudinal mode is changed into a single mode, and index guide structure is formed, thus reducing astigmatism.

Filed: 1980-09-16
Abstract: PURPOSE:To reduce the maximum frequency dividing number of a programmable frequency divider, by providing a means dividing the input signal or the output signal of the programmable frequency divider in terms of frequency. CONSTITUTION:A programmable frequency divider 2 divides the output signal of a clock signal generating circuit 1 by a frequency dividing number set by a setting circuit 3, and the output signal of the frequency divider 2 is converted to a signal of 50% duty cycle by a 2 frequency dividing circuit 4. A clock signal varying circuit 5 selects whether the output of the clock signal generating circuit 1 is applied to the frequency divider 2 after being divided to 1/M or is applied to the frequency divider 2 as it is; and when the frequency difference between adjacent frequencies of the frequency divider 2 is the 1/M of allowable frequency deviation, the clock signal is divided to 1/M and is applied to the frequency divider 2. Since the frequency dividing number of the frequency divider 2 is 1/M, the maximum frequency dividing number becomes small.

Abstract: PURPOSE:To permit an impurity atom concentration profile to be uniformed and an excellent active region without striation to be formed by selectively applying a laser or electron beam to a part to be an active region on a semiconductor substrate to fuse on heating. CONSTITUTION:A p type InSb monocrystalline substrate 12 having striation 11 is made from an InSb crystal ingot. Laser beams are applied to portions to be active regions on the substrate 12 to fuse and recrystallize for forming active regions each having a uniform impurity atom concentration profile. After Si ions are implanted into each region 13, a junction 14 shallower than the region 13 is formed by heat treatment. Then a lead wire 15 is connected to each junction 14 to prepare a semiconductor device having a photovoltaic element 16. Because the region 13 of the semiconductor device thus obtained has a uniform impurity atom concentration profile, a depletion layer 17 has no striation 11. Therefore, the carrier life is improved, and excellent element-characteristics can be obtained.

Abstract: PURPOSE: To compensate potenital change snd enable change of the charged member with time to be compensated by controlling grid voltage according to the characteristic change of a photoreceptor.  
     CONSTITUTION: A capacitor C 1  is inserted in series to a zener diode ZD 1 . According to this, a capacitor C 1  is charged by grid current and the voltage of the grid G incerases with time, thus the decrease in the photoreceptor potential is compensated. However, the photoreceptor potential saturates and therefore a Zener diode ZD 2  is parallel connected with the capacitor C 1  to limit to correcting voltage by the capacitor C 1 . Further a resistance R 1  is connected parallel with the capacitor C 1  and the charge of the capacitor C 1  is discharged through the resistance R 1  when the photoreceptor PC is no more used, whereby the correction voltage is reset to zero. In this way, the grid voltage is controlled in accordance with the change of the charged member with time and therefore the change of the charged member with time may be corrected.
